Aune S17 Pro EVO – Class A Headphone Amplifier
30.12.2024 09:20
Aune has introduced a new headphone amplifier, the Aune S17 Pro EVO. The model is suitable for headphones with a nominal impedance of 32 to 600 Ohms and is equipped with balanced outputs.
The output stage of the Aune S17 Pro EVO uses two pairs of transistors connected in parallel in each channel, which makes up a total of 16 output elements. The volume control is implemented on an R2R matrix, which provides precise control of the signal level.
The cooling system with internal radiators and a massive metal plate effectively dissipates heat, maintaining stable Class A amplification. The power supply of the device is equipped with a 50 W toroidal power transformer and capacitors in the filter with a total capacity of 19,200 μF. The Aune S17 Pro EVO headphone amplifier delivers 7.5W of output power when driving headphones with a nominal impedance of 32 ohms.
Aune S17 Pro EVO power into 6.35 mm (Low Gain): 32 ohms – 738 mW, 100 ohms – 266 mW, 150 ohms – 177 mW, 200 ohms – 133 mW, 250 ohms – 106 mW, 300 Ohms – 88 mW, 470 Ohms – 56 mW, 600 Ohms – 44 mW. 4-Pin XLR Output Power (Low Gain): 32 Ohms – 2880 mW, 55 Ohms – 1764 mW, 90 Ohms – 765 mW, 100 Ohms – 1000 mW, 150 Ohms – 694 mW, 200 Ohms – 520 mW, 250 Ohms – 416 mW, 300 Ohms – 347 mW, 470 Ohms – 221 mW, 600 Ohms – 173 mW. 6.35 mm Output Power (High Gain): 32 Ohms – 2050 mW, 100 Ohms - 688 mW, 150 Ohms - 464 mW, 200 Ohms - 348 mW, 250 Ohms - 282 mW, 300 Ohms - 235 mW, 470 Ohms - 150 mW, 600 Ohms - 117 mW

SPEC RSA-EX1000 – integrated amplifier in a case made of maple and spruce
The Japanese company SPEC CORPORATION has introduced a new integrated amplifier SPEC RSA-EX1000. The model uses a main board designed to minimize the length of the passage of musical signals from the volume control to the low-pass filter - according to the manufacturer, this preserves even the weakest signals and ensures a wealth of detail. Of course, the sound quality is also improved by reducing the inductance (coil effect) due to the minimization of internal wiring.

Definitive Technology Demand D11 – compact bookshelf loudspeakers with a bunch of innovations
The Definitive Technology Demand D11 bookshelf speakers use a dual suspension system of the BDSS mid/low-frequency driver, in which the 165 mm polypropylene diffuser is attached to the basket not only along the outer edge. In this case, the second suspension in the center of the system connects the inner edge of the diffuser with the core, which contains a proprietary waveguide - this design significantly improves the linearity of the diffuser movement.
